🔥 TWISTED STREET™ 4R70W / 4R75W / 4R75E

Ford 4R70W • 4R75W • 4R75E

350–450 HP

DAILY DRIVER • LIGHT TOWING • STREET PERFORMANCE

The Twisted Street™ is our upgraded street build for stock and mildly modified Ford applications. We take the known wear and hydraulic issues in the 4R70W/4R75 family and address them during the rebuild instead of simply installing a stock overhaul kit and sending it out the door.

Built for dependable everyday driving, better holding capacity and clean, consistent shifts.

Every transmission is built in-house and matched to your vehicle, engine and intended use.

🔧 WHAT WE UPGRADE

CLUTCHES & BANDS

✔ High-Energy Performance Frictions

✔ New Steels

✔ Increased Clutch Capacity Where Applicable

✔ Wide High-Energy Overdrive Band

✔ New Reverse Band

Why: The factory 4R70W/4R75 clutch and band system works well in stock applications, but additional heat and torque increase wear. We upgrade the friction system for better holding capacity and heat resistance.

INTERNAL HARD PARTS

✔ Updated Intermediate One-Way Clutch / Mechanical Diode Where Applicable

✔ New Low/Reverse Roller Assembly

✔ Updated Internal Parts Based on Year & Application

✔ Critical Bushings, Bearings & Thrust Surfaces Inspected and Replaced as Required

Why: Ford updated this transmission family throughout production. We build to the correct year/application and incorporate the appropriate updates instead of treating every 4R70W and 4R75 as the same transmission.

VALVE BODY

✔ Performance Shift Correction

✔ Valve Body Inspected & Reconditioned

✔ Known Hydraulic Wear Areas Addressed

✔ Cross-Leak Corrections

✔ Street-Calibrated Shift Timing & Pressure

Why: Valve-body wear and hydraulic leakage can cause soft shifts, delayed engagement and clutch/band failure. The Street calibration improves hydraulic control without turning your daily driver into a neck-snapping race transmission.

PUMP

✔ Pump Completely Disassembled & Inspected

✔ Pump Clearances Checked

✔ Pressure-Regulator System Inspected

✔ Pump Updates Performed as Required

✔ Final Hydraulic Pressure Verified

Why: Good clutches don't mean shit without proper oil pressure. The pump and pressure-control system have to support the rest of the build.

⚡ ALL NEW ELECTRONICS & SENSORS

✔ New EPC / Pressure Control Solenoid

✔ New Shift Solenoids

✔ New TCC Lock-Up Solenoid

✔ New Internal Wiring Harness / Lead Frame

✔ New MLPS (Manual Lever Position Sensor)

✔ Output Speed Sensor(s)

🔄 LOCK-UP TORQUE CONVERTER INCLUDED

✔ Heavy-Duty Lock-Up Converter

✔ Approximately 1,600–2,200 RPM Stall — Application Dependent

✔ Stall Matched to Vehicle & Engine Combination

Available upgrades include higher stall, anti-ballooning, billet-cover and multi-disc lock-up converters.

🚙 COMMON APPLICATIONS

Mustang • F-150 • Expedition • Explorer • Mountaineer • Crown Victoria • Grand Marquis • Marauder • Town Car • E-Series • Police Interceptor • Ford Performance Swaps

Exact transmission configuration varies by year, engine, drivetrain and vehicle. VIN/application verification is required before build.
